Lighting: You could spend as little as $200 for some fluorescent lights and up to $2,000 installing recessed lighting. Don't skimp on getting some decent lights. Lights that don't shine directly down work great. We recommend something that is indirect or dampened somehow. Finished basements often have low ceilings. The lighting can be harsh on the eyes if you're looking sitting down relaxing.
Finishing a basement can cost between $25–$50 per square foot on average, depending on how the basement is finished, whether any challenges come up or whether there are special circumstances with the project. For this reason, a 1,000-square-foot basement can cost up to $50,000 or more to finish. Virgil Miranda of Virgil Miranda’s Construction, a general contracting company based in New Bedford, Massachusetts, says it can be tricky to estimate remodeling jobs based on square footage alone, due to the variance in each job. Larger basements may have a lower cost per square foot than tiny remodel jobs.
How fast the job needs to be completed has a significant impact on the final price. A professional team can take a basement from framing to complete in about 45 days. A DIYer typically needs more time. If things need to be inspected, inspectors work on their own schedule, and if concrete needs to be poured, time must be allotted for it to properly set.

Once you’ve completely waterproofed and your basement is protected, you can move on to the room’s interior. Choosing the right flooring is an important part of making your finished basement truly your own. The type of flooring material you choose will definitely factor into your final price, so choose wisely and pick the floor that’s best for your finished basement.
If you decide to go with a pony wall, you may be able to handle the project yourself (saving money). However, if you’re going to expand your house and need to install weight-bearing walls, you’re better off leaving it to the pros. Additionally, you or your pro will need to investigate building codes and local requirements to ensure you comply with structural guidelines.

Your foundation should be inspected prior to finishing your basement. You don’t want to cover up any structural damage that would be identified in an inspection by installing framing and drywall. If items such as pipes have rust, the problem may be humidity instead of a leak, but it can be just as damaging. Waterproofing the basement and using a dehumidifier helps reduce dampness and the risk of mold development.


The cost of a basement remodel can be significant, but your potential return on investment is just as considerable. In addition to adding to your living space, the average basement remodeling project also increases your home's resale value. The National Association of Realtors considers basement remodels to be among the most valuable home renovations.
You can fit a full bathroom with tub/shower combination in a room that measures 40-square feet. However, on average, a smaller bath (with just a stand-up shower) or a half-bath usually needs to be about 30-square feet for comfort and functionality. Depending on the basement space and layout, you may be able to go with a larger 60-square feet or more bathroom space. Creating bathroom with a separate water closet may require 100-square feet or more.
Drywall must be applied to any framed basement walls you have and must be applied to any additional walls used to create your basement bedroom. A standard 8’ by 4’ panel will cost between $10 and $20, depending on the thickness. The cost to install these panels varies, but most homeowners report spending around $1.50/sf. The total cost of your project will range between $1,152 and $1,982, with an average cost of $1,915 to install a wall.
